... AND8076 Low Standby Power Supply with the NCP120x Series Prepared by: Christophe Basso ON Semiconductor INTRODUCTION The NCP1200 represents one of the cheapest solutions to build efficient and cost-effective Switch-Mode Power Supplies (SMPS). As this design example will show, the part definition does not confine the component in low-power applications only, but it can actually be used in Flyback and Forward supplies for virtually any output power ...

Self-Powering the Controller in Standby An auxiliary winding does not usually cause any self-supply problem with a continuous pulses flow. In standby, whatever implemented frequency reduction techniques (e.g. skip or frequency foldback), the recurrence between pulses can become very low. ...
